I love the shader. On top of that I’m really impressed, that it works just by replacing hlsl code out of the box.
Is there a way to make additional lights (point/spot etc) to also influence the shadow part like the directional light does? In other words: Can we get Nicolas Cage also from the shadow of the other lights?
At first I thought that mentioned specular setting does that, but during the tests I realized that is not the case.
I know that this shading model is made for your game (I also wishlisted it), so the way it works now it tweaked to suit its purposes, but is it actually possible or is there any technical limitation?
